The FGen Program, version 2.00
Try DAP Measurement Studio (DAPstudio). DAPstudio supports all the functionality of FGen in an integrated data acquisition package.
Analog inputs often contain unwanted frequency components. All unwanted frequencies below half the sampling rate can be removed by digital filters. The DAPL operating system has built-in commands to perform filtering on acquired data. The DAPL filtering commands implement Finite Impulse Response (FIR) filters by applying vectors of coefficients, called filter vectors, to acquired data. (To implement the classic filter responses - Bessel, Butterworth, Chebyshev, Elliptic, and inverse Chebyshev - in DAPL, use the DAPL IFM.)
The filter generation program, FGen for Windows, version 2.00, allows design of multiple filters for use with the DAPL
The earlier version, FGEN for Windows 1.01, is included with each DAP shipment with the DAPtools Basic software package. It can produce several filter types: lowpass, highpass, bandpass, bandstop, and running average, with Blackman, Hamming, and Hanning windowing. FGen also provides plots of filter response as dB vs. frequency and as amplitude vs. frequency.
